MACHINE-GUN.

Specification of Letters Patent.

1 Patented Dec. 27, .1921.

Application filed June 22, 192 1. Serial No. 479,488.

' T 0 all whom it may concern:

Be it known that I, ALBERT E. F Lonroim,

a citizen of the United States, residing at New York, in the countyof New York and State of New York, have invented certain new and usefullmprovements in Machine- Guns, of which the following is a specificain the production'of multiple machine guns "capable of being simultaneously fired a plurality of times without reloading.

A further object is in the provision of means' for supplying revolving cartridge 'ient manner.

carriers to all of the several guns at one operation and in a rapid, safe and conven- These objects are secured by the novel construction and disposition of parts as hereafter related and shown in the draw- 111g accompanying, forming an essential part of this disclosure, and in which Figure 1 is a plan view of a machine gun made in conformity with the invention.

Fig. 2 is a broken horizontal sectional view of the same, drawn to an increased scale.

Fig. 3 is a top plan view, showing a pair of the revolving cartridge holders.

Stated in general terms, this machine gun consists of several barrels, twelve being indicated, so disposed on a fixed level plane as to cover an extended range, each barrel being served by a geared rotative cylindrical cartridge carrier having openings in alinement with its corresponding barrel and adapted to be revolved in unison.

These carriers are removably engaged in a casing, thereby being handled as a unit and the several bullets are discharged from the cartridge shells by percussion means actuated by a single crank which also rotates the carriers intermittently.

Referring to the drawings, the numeral 10 designates a hollow rectangular body having on its front side a plurality of angularly faced bosses 11 screw threaded to engage the gun barrels 12 set to radiate outwardly as shown, the center barrels being substantially in parallel and all disposedin the same level plane.

A corresponding number ofhollow rectangular extensions 14 are fixed to the opposite side of the body 10, their purpose being further on apparent.

Neatly fitting the chamber in the body 10,

'riphery and and enterable through its open top, is a casing 15, having apertures 16 register-ablewith the bores of the gun barrels 12 at itsends for manipulative purposes.

Disposed in the casing are cylinders 18 interengaged by spur gear teeth ontheir pebored axially to receive a; helically coiled compression spring 19, the spring abutting itsends against hardened balls 20 carried atthe ends of the bore and impinging in concave recesses 21 in the 0pposite side walls of the casing, the balls acting as pivots on which the cylinders rotate.

Formed in the'cylinders are openings 22 to receive the cartridge 23, these openings being evenly spaced and bored at an inclination corresponding to the angularity of the gun barrels 12, converging rearwardly as shown.

At about the middle of the body, a spindle 25 engages one of the cylinders in such manner as to transmit rotary motion, the outer end of the spindle having a gear 28 fixed upon it, meshing a mating gear 29, mounted in a shaft 30 and containing a pawl and ratchet driving device (not shown) permitting the shaft to be rotated in one direction without movement of the gear but being driven by it when oppositely rotated, and in the outer end of the shaft is afiixed a crank 31 by which the cylinders may be manually operated. Also fixed to the shaft 30 is a pinion engaging a rack 33 formed on the lower side of a bar 34 passing slidably through the several extensions 14 and guided by pins 35 set in the extensions and operative in slots 36 in the bar.

One end of the bar 34 extends outwardly and is provided with a head 37 against which is exerted the pressure of a compression spring 38 encircling the bar and abutting against the outermost extension, thus tending to draw the bar toward one end of the device.

Mounted on pins 40 set in the extensions, are levers 41 formed with catches 42' at one end and having projecting angular arms terminating in hammers 43 adapted to detonate the cartridges, the hammers entering the body and casing through appropriately formed openings 44 when drawn thereagainst by pull springs 45 fixed at their respective ends to the levers and pins set in the extensions.

Mounted on pivots 46 are trigger pawls 47 adapted to engage the catches 41, as the bar is moved to the right, and enter recesses 48 formed in the bar upon its return movement.

In operation, a set of the cylinders having been supplied with cartridges, the same are inserted, in meshed condition, in the cas- Y ing and the latter is entered into the chambered body by the handle 17.

The crank 31 is given an oscillatory motion, causing the cartridge in the bored chambers 22 to aline with the bore of the gun barrels, whereupon the crank is turned in the opposite direction, raising the hammers due to movement of the bar carried pawls until the pawls have passed the catches, and permitting the springs 45 to forcibly throw the hammers against the cartridges. Y v 7 Further movement of the crank in an opposite direction recocks the pawls and rotates the cylinders in a manner easily understood.

I From the foregoing it will be seen that an effective weapon for battle has been disclosed, but it is within the scope of the appended claims to make modifications from the structure herein presented.

Having thus described my invention what I claim as new and desire to secure by Letters'Patent is 1. A machine gun comprising a body frame, a plurality of gun barrels extending from one side thereof, a casing removably engaging said frame, cartridge carrying cyling containin a compression spring, bal in I the opening a utting said spring, said balls engaging recesses in said casing whereby said carriers are rotatably centered, means for rotating said carriers, and means for detonating cartridges therein.

In witness whereof I aflix my signature.

ALBERT E. FLORICKE.
